Abstract
Disclosed in certain embodiments are processes for heavy hydrocarbon removal that implement a regeneration loop that introduces an absorbent into a regeneration gas stream, and systems for implementing the same.
Claims11
A process comprising:
- introducing a gas feed stream comprising C5+ hydrocarbons or organic sulfur species into a first adsorbent bed to produce a treated gas stream;
- regenerating a second adsorbent bed with a portion of the treated gas stream to produce a regeneration gas stream;
- introducing an absorbent into the regeneration gas stream to remove a portion of the C5+ hydrocarbons or organic sulfur species;
- subsequently removing the portion of the C5+ hydrocarbons or organic sulfur species from the regeneration gas stream to form a separated regeneration gas stream;
- and
- subsequently mixing the separated regeneration gas stream with the gas feed stream.
